Battery Safety Notes

WARNING!

Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed only by authorized
personnel.

Chemical Hazards

Any gelled or liquid leakage from a valve-regulated lead-acid (VRLA) battery contains dilute sulfuric acid,

which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and
corrosive.

To avoid injury:

Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel •
knowledgeable of batteries and the required safety precautions.

Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic •
objects from hands and neck.

Batteries produce explosive gases. Keep all open ames and sparks away from batteries.•

Use tools with insulated handles, do not rest any tools on top of batteries.•

Lead-acid batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or •
other reproductive harm. Battery post terminals and related accessories contain lead and lead compounds. Wash

hands after handling (California Proposition 65).

Wear protective clothing (insulated gloves, eye protection, etc.) when installing, maintaining, servicing, or replacing •

batteries.

If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your company’s •
approved chemical exposure procedures.

Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with a solution •
of one pound bicarbonate of soda to one gallon of water. Report a chemical spill using your company’s spill reporting
structure and seek medical attention if necessary.

Always replace batteries with those of an identical type and rating. Never install old or untested batteries.•

Do not charge batteries in a sealed container. Each individual battery should have at least 0.5 inches of space •
between it and all surrounding surfaces to allow for convection cooling.

All battery compartments must have adequate ventilation to prevent accumulation of potentially dangerous gas. •
Ventilation should prevent trapped hydrogen gas pockets from exceeding a 1% concentration as per regulation 70E

of the National Fire Protection Agency (NFPA).

Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have developed •
on your body.

Never use uninsulated tools or other conductive materials when installing, maintaining, servicing, or replacing •
batteries.

Use special caution when connecting or adjusting battery cabling. An improperly connected battery cable or an •

unconnected battery cable can make contact with an unintended surface that can result in arcing, re, or possible

explosion.

A battery showing signs of cracking, leaking, or swelling should be replaced immediately by authorized personnel •
using a battery of identical type and rating.

Equipment Cautions

Do not operate NiCd and lead-acid batteries in the same room. NiCd emissions will neutralize the lead-acid solution, •
rendering the battery useless.

Overcharging the battery can result in a loss of capacity and excess release of gas.•

Recycling and Disposal Instructions

Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose of the
batteries in accordance with all federal, state and local regulations.

1.3 Operating Conditions

Because SMU-C batteries, which are valve regulated and virtually sealed, do not give off
perceptible amounts of gas under normal operating conditions, they can be installed in the
same environment where people live and work.

Acceptable ambient operating temperature: -40ºF to 131ºF (-40ºC to 55ºC)•
Ideal ambient operating temperature: 68ºF to 77ºF (20ºC to 25ºC)•
Ambient humidity: ≤ 95%•
Operating room or area: ventilated and not fully sealed •

1.4 Capacity

Battery capacity is rated in Ampere hours (Ah) and is the quantity of electricity that can be
supplied during discharge (See Table 1-1).

The actual capacity is related to the utilization ratio of the active positive and negative

materials within the battery. The utilization ratio is inuenced by the depth of discharge, the

structure of the battery, and the manufacturing technology. During normal usage, the factors

that inuence the actual capacity are discharge rate, depth of discharge, end voltage, and

temperature.

The higher the discharge rate, the lower the available capacity.•
As batteries get colder, the available capacity is reduced. This is related to the kinetics of •

the electrochemical reactions and the resistivity of the electrolyte (See Fig. 1-1).

NOTE:

Although the battery can be operated at temperatures below 5ºF (-15ºC), the capacity and ability to
discharge will be dramatically decreased. Similarly, temperatures approaching 122ºF (50ºC) will increase

water loss and corrosion of the plates, resulting in a shorter battery life.

1.5 Temperature and Battery Life

High temperatures can harm the battery and reduce its lifespan. Battery life decreases by

50% per 15ºF (~ 9ºC) above the standard operating temperature of 77ºF (25ºC).

To minimize battery damage:

Use temperature compensated chargers.•
Never allow the battery's temperature to exceed +131ºF (+55°C).•
Make sure operating area is properly ventilated, so heat cannot accumulate.•
Provide at least 0.39" (10mm) of space between batteries to enhance convective cooling.•
Visit sites annually to check for shorted cells, improperly set voltages, lter cleaning on •

ventilation systems, etc.

1.6 Internal Resistance and Short-circuit Current

The internal resistance of the battery is affected by temperature and charge state. The
internal resistance is lowest when the battery is fully charged.

NOTE:

Take measurements before and after charging and during discharge to help track changes and problems. Use

a form (see Section 6.0), to record the results. Wait two hours after charging before taking nal measurements
in order to allow the electrolyte to cool sufciently.

CAUTION!

If the heat generated as a result of charging exceeds the rate at which heat can be transferred out
of the battery, thermal runaway can occur and excessive overheating will result.

NOTE:

Refer to your particular charger’s manual for specic instructions regarding charger setup and operation.

2.1 General Charge

The limited current and constant voltage recharge method, also known as the modied
constant potential method, satises the need to have the battery quickly recharged while

ensuring maximum battery life. Figure 2-1 shows the relationship between current, voltage,
and charge for the SMU-C 12-100.

When to Charge

After installing or discharging the battery.•
If the battery has been stored for more than three months and the open circuit voltage is •

lower than 12.6V/block.

12

General Charge Procedure

Charge the batteries with a constant current no greater than 0.2C1.

voltage of 13.8V/block at 77ºF (25ºC) is reached.
Continue charging, reducing the current to maintain a constant voltage of 13.8V/block.2.

Fast Charge Procedure

Charge the batteries with a constant current no greater than 0.2C1.

voltage of 13.8V/block at 77ºF (25ºC) is reached.
Continue charging, reducing the current to maintain a constant voltage of 13.8V/block.2.
The batteries will be fully charged in 18-24 hours when the voltage is a constant 13.8/3.

2.2 Floating Charge

A oat charge keeps the battery in a fully charged state with a small but constant current to

automatically cover capacity loss resultant from self discharge and other discharges.

At 25ºC, the proper oating voltage for the C series is 13.68V/block. The temperature
compensate coefcient is -32.4mV/ºF/block (-18mV/ºC/block).

Table 2-1, Floating Voltage at Different Temperatures

CAUTION!

If the oating voltage is higher than indicated in Table 2-1, then the oating current is also higher
than ideal and will accelerate corruption of the grid and shorten the life of the battery. If the oating

voltage is lower, the battery will not be kept in fully charged state, which will crystallize the PbSO4

(Lead Sulfate), decrease the capacity, and also shorten the life of the battery.

2.3 Discharge

The end voltage is the lowest voltage the battery can be discharged to without causing
damage. Usually, the 20 hour rate (C20) end voltage of a C battery is 10.5V/block. Although
the battery can be discharged below this voltage, doing so will not discharge any more
capacity and can affect its lifespan. It may be impossible to recharge a battery after several
over-discharges. After a discharge, recharge the batteries as soon as possible to maximize

battery life. See Section 5.0 for discharge specications.

All lead acid batteries experience self-discharge while in open circuit storage. This causes circuit

voltage and capacity to decrease (see Fig. 3-1).

During storage please note:

The self-discharge rate is related to ambient temperature. The lower the temperature, the less •
the discharge. Batteries should be stored in a clean, ventilated, and dry location with an ambient

temperature of 32ºF to 95ºF (0ºC to 35ºC).

It is important to track open circuit voltage which is related to the density of the electrolyte. If the •
open circuit voltage is lower than 12.6V/block, or the batteries have been stored for three months,

the batteries should be charged to avoid damage caused by self-discharge.

All batteries should be fully charged before storage. Record the storage date and next •

supplemental charge date in a maintenance record (See Fig. 4-2).

4.0 Maintenance

4.1 Recommended Maintenance Tasks

In order to prolong battery life, perform regular maintenance and inspections.

Monthly Maintenance

Keep the batteries and battery room clean.•

Measure and record the ambient temperature of the battery room.•

Check for damage and overheating evidence on the terminal, container, and lid.•

Measure and record the total voltage and oating current of the battery system.•

Quarterly Maintenance

Measure and record the oating voltage of every on-line battery. If the voltage of

more than two cells is less than 13.0V after temperature adjustment, discharge the

battery and then recharge at the oat rate. If the problem still exists, conduct yearly

or three-year maintenance procedures. If the problem persists, please contact Alpha
Technologies.

Yearly Maintenance

Check for loose connections.•

Conduct a discharge test to check the exact load, discharging 30-40% of the •
rated capacity.

Three-Year Maintenance

After three years of operation, conduct an 80% capacity test annually.
